Answer
The student followed incorrect order of operations. First, the student subtracted instead of evaluating the values in parenthesis first. Then, the student add 57.41 and 5.47 instead of multiplying.
Work Step by Step
Recall, according to PEDMAS, parenthesis are always the first order of operations. The correct method is as follows:
$$=60.41-3(.4+5.07) \\ =60.41+(3)(5.47) \\ =60.41+16.41\\ = 76.82$$
